The sound sensor is used to check the size and sound quality of the dynamic bounce sound of the double-sided teeth in operation. Even if the belt is slightly peeled off, it will produce abnormal sounds and irregular sounds, which can be distinguished by the sound sensor.
A sound meter is used to check the size and sound quality of the moving elastic sound of the running belt. Even if the belt is slightly peeled and damaged, it will emit abnormal sound and irregular sound, which can be distinguished by the sound meter.
Using hearing to identify irregular operations is a very common method. For example, using an electronic stethoscope to detect abnormal noise in a part is often the method used by experienced operators.
If the belt is in a good continuous rotation state, it will make a low whine sound. If there are sharp hissing noises, squeaking noises and other irregular sounds, it often indicates that the belt is in bad continuous rotation.
The sharp creaking noise may be caused by improper lubrication. Improper belt clearance can also cause metallic noise. The indentation of the concave track on the double-sided tooth synchronization outer ring track will cause vibration and cause a smooth and crisp sound. If it is because of the knocking scars caused by the installation, noise will also be generated, and this noise will vary with the speed of the belt.
If there is intermittent noise, it means that the moving parts may be damaged. This sound occurs when the damaged surface has been rolled out for a long time, and if there are pollutants in the double-sided tooth synchronization, it will often cause a hissing sound. Severe damage to the same bearing will produce irregular and loud noise.
